What is debt finance?

How a lender thinks, and why it differs so completely

An equity investor asks how large this could become. A lender asks a narrower question: will I be repaid, and what happens if I am not?

That difference is structural rather than temperamental. A lender's upside is capped at the interest rate whether the business triples or merely survives. No amount of potential compensates for elevated risk, because the lender cannot participate in it. This is the entire explanation for a pattern founders find maddening — a bank declining an exciting business while lending to a dull one. The dull business has predictable cash flow and security. The exciting one is asking a lender to take equity risk for lending returns, which its own cost of funds makes impossible.

Understanding this converts a decline from a judgement into information. It usually means the request went to the wrong layer of the market, not that the business is unfundable. The African capital stack maps who sits where.

What lenders actually assess

Cash flow. Not profit — cash. A lender wants to see that the repayment is comfortably covered by money actually arriving, in a bad month as well as a good one. Debt service cover is usually the first number calculated and often the last one that matters.

Security. What can be realised if repayment fails: property, equipment, vehicles, debtors, stock, or a personal surety from the owner. Security does not make a bad loan good, but its absence makes a marginal one impossible.

Track record. How long the business has traded, whether it has borrowed and repaid before, and whether its accounts reconcile. A business with three years of audited financials borrows on materially better terms than an identical business without them.

Character and conduct. Old-fashioned and still decisive, particularly in relationship-driven markets. How the account has been run, whether previous facilities were honoured, whether bad news arrived early or late.

Secured, unsecured, senior and subordinated

Secured borrowing is backed by a specific asset the lender can take and sell. Cheaper, because the downside is covered.

Unsecured borrowing has no such backing and prices accordingly — often several times higher, which is not exploitation but arithmetic about recovery rates.

Senior debt ranks ahead of other creditors for repayment. Subordinated debt sits behind it, accepts more risk, and is priced higher; mezzanine lives in this territory.

The ranking is not theoretical. If a business fails, this order determines who recovers anything at all, and shareholders are last. It is why terms that look like technicalities — a cession of debtors, a negative pledge, a personal surety — are the most consequential clauses in a facility agreement. Each is about queue position. Security, covenants and surety covers them in detail.

When debt is clearly the right answer

Debt beats equity outright in several common situations, and founders reach for equity in all of them more often than they should.

When the need is short-term and self-liquidating — a confirmed order, an invoice, an import — transaction finance repays itself from the transaction it funded. When the capital buys an asset that generates the cash to repay it, the asset secures its own funding. When the business is profitable, stable and has security, borrowing preserves ownership of a company that is already working. And when the amount is modest, the cost and dilution of an equity round rarely justify it.

The reverse also holds. Debt is the wrong instrument when cash flow cannot service repayment on a bad month, when the business is pre-revenue, and when the capital funds experimentation rather than execution. Debt is unforgiving of uncertainty, which is exactly what it is priced for.

What determines the rate you are offered

Two businesses with identical revenue are routinely quoted very different rates, and the spread is driven less by quality than by three mechanical factors: how much security covers the exposure, how long the facility runs, and how easily the lender can verify the numbers. A business with audited financials, a documented debtor book and property to pledge is simply cheaper to underwrite than an identical business without them.

That is the most actionable fact in this lesson. A founder cannot change the prime rate, but can change how legible the business is — and legibility is worth more basis points than negotiation usually is.

The risk founders under-price

Equity dilutes ownership. Debt can end the business, and can reach beyond it.

A missed equity milestone produces a difficult board meeting. A missed loan repayment produces default, and default triggers rights that compound quickly — acceleration of the full balance, enforcement against security, and where a personal surety exists, a claim against the owner's own assets.

None of that is an argument against debt, which remains the cheaper capital for most established businesses. It is an argument for sizing it against a pessimistic forecast rather than an expected one, and for reading the default and surety clauses at least as carefully as the interest rate.
